Powder Rehydrator SII-AL-M15

The SII-AL-M15 Hybrid Powder Mixer is a highly efficient and mobile two-stage in-line mixer, designed to rapidly dissolve powders and blend them homogeneously with liquids. Thanks to its advanced design, this mixer operates with a single motor capable of pumping the resulting mixture at pressures up to 5 bar. It not only offers versatility and ease of use, but also represents a cost-effective mixing solution; engineered to handle high dry matter concentrations, it guarantees uniform, high-performance mixtures, ideal for demanding applications.

APPLICATIONS

●The SII-AL-M15 Hybrid Powder Mixer is especially suitable for incorporating thickeners, stabilizers, and emulsifiers at concentrations required in most hygienic applications across the dairy, beverage, and food industries.
●In addition, its robust performance makes it ideal for milk recombination with dry matter concentrations above 50%, meeting hygienic application requirements for precision and efficiency.

Key Benefits

Rapid and Homogeneous Dissolution: Ensures optimal product quality by fully dispersing powders without lump formation.
Mixer and Pump in One: Compact and mobile equipment combining mixing and pumping in a single unit for easy implementation.
Dynamic Shear and Gentle Mixing: Preserves the integrity of the processed product through a controlled shear regime.
Cost-Effective Operation: Lower installation, energy, emissions, and maintenance costs compared to conventional multi-equipment solutions.
TCO Reduction: Reduces total cost of ownership by combining mixing and pumping in a single high-efficiency unit.
CIP-Flexible: Functions as a discharge pump or recirculation pump for cleaning-in-place (CIP).

Efficient solution for powder mixing and liquid pumping.

STANDARD DESIGN

TWO-STAGE CONFIGURATION

Two-stage pump configuration.

•First stage: rotor-stator for efficient powder mixing
•Second stage: impeller for high-pressure transfer

SII-AL-M15 Powder Rehydrator — Standard two-stage design: rotor-stator and pump impeller

STANDARD DESIGN

Hygienic C-ball valve that isolates the injector system, which pre-mixes the powder with the liquid to create negative pressure at the funnel outlet, thereby optimizing powder feeding and dissolution.

The liquid flow from the recirculation loop creates and maintains a vacuum in the ejector.

STANDARD DESIGN

The unit is mounted on a durable stainless steel frame and includes a sliding table that facilitates the placement of powder bags during mixing, and also serves as a lid when not in use.

OPERATING PRINCIPLES

This two-stage mixer is normally integrated into a batch tank recirculation loop.

First, liquid circulates through the mixer, drawing powder from the funnel and injector. This generates negative pressure that pulls powder into the rotor-stator, where it is dynamically blended with the liquid.

The pump impeller then applies a final shear stage, delivering a homogeneous mixture at high pressure back to the tank.

For large tanks (over 1–2 m³), installing a Rotary Jet Mixer is recommended to further improve overall mixing efficiency.

Once mixing is complete, the SII-AL-M15 can operate as a discharge pump or as a recirculation pump for cleaning-in-place (CIP), which simplifies cleaning and maintenance when used alongside rotary jet mixing systems.
